Because if Haman has to change the plan again, it will take longer for Helix to update. The leather clothing is worth it for the downswing you say, then it will be worth it to get next turn as well.
Changing 1 green doesn't really change the text of the update at all. And look at last turn- Helix isn't going to get the update out slower because of a tiny change like that. We were making changes up until the end and Helix was happy since it made it look like there was less of a delay.
Now, the next part I could see you making that argument for, but not for 1 green.
As far as they know, he did not cost them $9000
Aye, but the mistake almost cost them 9k. From their point of view, they got very lucky that the mistake happened after the payment and not before, but as far as I can tell there's nothing to indicate that it couldn't happen earlier. Well, I guess it's kinda the opposite, but that sort of money is still very significant. Plus, I kinda doubt that they don't have programs set up that will detect the 9k overpay that we're making it appear someone else did. (whoever we're swapping with) We may be able to change that one as well, but now we're just adding more and more things on.
Then again, there's a good chance their software doesn't double-check things, which would mean we're safe. Cheap outsourced software for the win? Not to mention they can still talk to the neighbors and they'll agree that it certainly sounded pretty bad. They might wait a few days before contacting their worker- it's been a month, surely the police can wait another few days.
I seriously think that the improved kevlar plan is much better. Either remove the damage entirely (15 cubes) and things appear pretty good- they have a question (why did they buy a ton of kevlar), and get an answer. Remember, buying kevlar isn't illegal. We show them that we had a legitimate reason for doing it, they'll get off our backs. More importantly, it doesn't involve us trying to mess with another company's systems- systems that we may not fully understand.
If you want to be risky don't remove the damage at all and go for the 'failed test' plan. This has the potential of not needing any cubes lost beyond the enchantment research itself (something that we want to get done anyway).
While we might get a little attention, it will be positive attention. And we own a moderately large courier business, there's no way we'll be totally anonymous. If we open up the restaurant, we'll be so clearly not anonymous it won't even be funny. A little attention on us won't hurt as long as we keep up the "it's not a viable product yet" and "we don't want to reveal our process".
I'll work on getting specific numbers if anyone cares, but I don't see how I can beat a 6-1 vote deficit. So my goal is to convince Elder Haman. Definitely not making the restaurant this turn though, can't afford the negative synergy with the police investigation, and the chance of getting the reduced payment is worth it.
